BRICK OR TILE MACHINE.

SPECIFICATION forming part of Letters Patent No. 507,798', dated October31, 1893.

Application led January 25, 1893. Serial No. 459i713 (N0 model- To a/ZZwhom it may concern:

Be it known that I, EGBERT M. FRnEsE, a citizen of the United States,and a resident of Galion, in the county of Crawford and State of Ohio,have invented certain new and useful Improvements in Brick or TileMachines; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make Aand use the same, referencebeing had to the accompanying drawings, which forni a part of thisspecication.

My invention relates to that class of brick or tile machines in whichbricks or tiles are automatically cut from a moving column or bar ofclay issuing from the die or dies of a clay working machine.

The prime object of my invention is to provide automatic cutting devicesdrivenvfrom the clay machine or other source of power, which act uponthe column or bar of clay to sever the bricks or other objectstherefrom.

It is also an object to provide improved frictional devices, whereby thespeed of the cutting mechanism is governed and regulated by the speed ofthe moving column or bar lof clay, any variation in the speed of theclay, causing a coriesponding variation in the speed of the cuttingmechanism.

There are other object-s which will be'apparent to those skilled in theart, and which need not be enumerated in detail.

The invention consists in the novel construction and combination ofparts, hereinafter fully described and claimed. l

In the accompanying drawings: Figure 1 is a plan view 0f a brick or tilemachine, constructed in accordance with my invention. Fig. 2 is a sideelevation of the same. Fig. 3 is a cross section, on the line 3 3, Fig.2. Fig. 4 is a cross section on the line 4-4, Fig. 2. Fig. 5 is acentral vertical section through the cutter carrying rings; showing twomodilications in the construction thereof. Fig. 6 is a plan view,showing means for driving the cutting mechanism. Figs. 7, 8 and 9, aredetail views showing the means for regulating the tension of the cuttingwires. Fig. 10 is a detail View showing the means for connecting one endof the cutting wires to the annuli. Fig. 11 is a view 0f the end of oneof the cutting wires.

In the said drawings, see Figs. 1 and 2, the

reference numeral 1 indicates the die of a clay working machine, and 2the belt which receives the clay as .it emerges from the die. This beltpasses over pulleys 3 and 4, respectively, fixed to shafts 3a and 42Ljournaled in the front and rear ends of a table, consisting of side'bars5, flush with the upper surface of the belt and supporting legs oruprights 7, s ecured to the base 7a'. Intermediate of their ends, theside bars are provided with rollers 8, for supporting the belt, andpreventing it from sagging. 'Journaled in bearings 9, secured to saidbase is a horizontal shaft 10, which is driven fromsome moving part ofthe clay machine, or other source of power, and

carries at its rear end a bevel pinion 12, which meshes with a bevelgear 13, mounted upon a transverse shaft 13, journaled in frames 14,secured to the cross pieces 15, of the base 7a. This shaft carries apulley 16, Fig. 2 around which, and a smaller pulley 17, fixed to atransverse shaft 18, journaled in said frame above and at one side ofsaid shaft 13a, passes a belt 1,9 for conveying the cut bricks or otherobjects, away from the feeding belt 2. This belt also passes overApulleys 20, located at the front and rear ends of a table, similar tothat which supports the feeding belt. This conveyer belt is locatedv atthe rear endof the feeding belt, so "as to receive the bricks as theyare cut.

Securely' bolted to brackets 2l, having hubs `23, which are'journaled onthe shaft 4a of the rear pulley 4, see Figs. l, 2, 3 and 4, is a casting24 preferably circular in form and provided with an eccentric or otherform of opening 25% of the feeding belt, so that its opening willregister with the moving column o r bar of clay, as seen in Figs. 1 and3. On its outer face, it is formed with a circular groove or recess 25h,in which is located a rotatable annulus or ring 26 having a series ofcogs upon its periphery. The meeting surfaces of the annulus and thecasting are formed with semicircular grooves 26 to receive balls 27, seeFig. 5, forming ball bearings for the annulus,

so as to reduce the friction to a minimum.

This casting is located just in rear IOO lar casting 52,` having anannulus 34, Fig.'5. This casting, and its annulus, are exact duplicatesof the casting and annulus before described, and further description istherefore not deemed necessary.

Journaled in bearings 35, formed in an eX- tension 21, of one of thebrackets 21,see Figs. 1, 2 and 6, to which the casting 24: s` bolted, isan inclined shaft 36, having near its rear end two pinions 37 and 38,which mesh respectively with the cogs of the two annuli 26 and 34E. Thisshaft aty its opposite or front end, is provided with a pulley 39, whichis connected lby means of ra looserbelt 40, with a pulley 41, on themain `shaft `10. See Figs. 1,2, 3, 4 and 6.

Pivoted to the base7, are two inwardlyfextendiuglevers 42, onev on`each-side. ofipulleyI .41, and provided at their innerer freer endsf4with `al tightening pulley 43,=whichi rests upon` -the beltAO. :See`Figs. 3 andai. {Cnetof the levers-42, `atitsiinner end, is; providedwithra cleat "45,1upon which rests one end ofran-in-l wardl'yfextendinglever 46,1fulcrumed 'upon the `#shaft 136, the opposite'or `outerrend,o'fj .which t is provided with aflloose bevel-pinion.'

It will be noted that thelwire engages with one of the notches in theyhand-wheel, thus preventing the hub from turning, the coiled springregulating the tension of the wire.

Secured to a bracket, on one side of the feeding table, see Fig. 3, isan inwardly ex- `tending spring arm 65, having a loop67, at its inner or"free end and carrying a wooden block 68, which lies in the path of thewires during their movement, and serves to clear the same from any dirtthat may be adhering thereto.

'Before describing the operation in detail, it should be statedvthat thecastings-and annuli,mustbe=inclined atzanacute angle to the path oftravelof `thecolumnof clay, asif theyy were -,perpendicular,` or atright angles thereto, an angular cut-would beV made, owingtowtheimovelnent ofthe clay. dtshould also be stated,;that the,cutting=-mechanismshould be soitin1ed,astorrotateormoveat-acertainrate, `with relation tto r.the movinygm` claywand -meansprovided,i1sothatfwhen thespeed of the clay-increases or decreasesitheffspeedof -thecutting ,devices must beacorrespoudinglyva ried, as otherwise, thebricksfcutawouldfnot beef .uniform thickness,fandthe,cutrwould `notbeperfectlyfstraight. rBearingthesestatelments inimindfthe.operationaisasfollows:

The speed .of -said pinions V48 and,'49 fbeingxvariedythe pinion .47 vwill be fforced eithemupwardlyordownwardly, turning lever 4:6, on itsffulcruln and causing thetightenerpulleyto bearwith more or less pressure on the belt 40, and, the' latterto bind tighter or looser on the pulley V41. If the clay andfeeding-belt be traveling too fast, the feed of the pinion 49, will beaccordingly increased, and run at a higher rate than pinion 48. Thesetwo pinions now moving at different rates will cause the `lever 46 toturn' on its fulcrum lin the direction of the least resistance of thepinion 47 on the end thereof. In this instance, the pinion 49, travelingthe faster, the resistance would be less in the direction of itsrotation and the inner end of the lever Will be depressed causing thetightener pulley to bearv with greater pressure on the belt, which willthen be Y. caused to bind more tightly on pulley 39, and

the speed of shaft 36 be increased until pinions 48 and 49 again rotateat the 'same speed.

If, on the contrary, the speed of the feeding belt decreases, a reversemovement will Ybe given to lever 46, easing thetightener pulley,

and. allowing the belt to slip on pulley 39 and its speed decreased. Asthe bricks are cut from the bar of clay, they pass onto the conveyerbelt. v v

I have described the castings and their annuli or rings as beingduplicates vofeach other, but-it is obvious that the outer casting andits annulus may be dispensed with, and. an ordinary wheel or even acrank be substituted therefor, with which the cutting wires may beconnected. In fact, any suitable de- Vice may be substituted therefor,which will accomplish the essential object of the invention, which is togive to the cutting wires a combined transverse and vertical movementdown through the bar of clay, and then around out of the path thereof,and up over the same to make a new cut. I have also illustrated the axisof the annuli or rings as being in a horizontal piane, but it is obviousthat the plane thereof, may be at an angle to the line of travel of theclay, without departing from the invention. Y

In the modification of the'annulus 34, and casting 32, the frictionballsY are dispensed with and a groove and ilange provided as in theordinary eccentric and its strap for actuating the valve of a steamengine. See Fig. 5. Having thus described my invention, what I claim isrl. In a brick machine of the character described, the combination withya conveyer, of two rotatable carriers, one of which has an openingcoinciding with said conveyer, and a horizontal cutting wire movingtransversely across and above and below the ,path of a column of claycarried by said conveyer, substantially as described. t v
